Using their long proboscis, Nektara Vezikos pierce through the thick skin of a cactus to feed on the water and nutrients within. The pale-colored sap they drink becomes colorful during the digestion process due to chemical reactions. This refined nectar is kept in a special sac and used both to feed young and as a stored fuel source for times when food is scarce. Research has proven that their colorful exoskeletons are not influenced by their diet, as was initially assumed. However, natural selection has led to most colonies matching the color of the cactus species they feed on. Rarely, more colorful bodies and nectar sacs are seen; these aphids are slightly poisonous because of the sap they consume from a toxic cactus species called Morta Spino. Nektara Veziko females give birth twice during their short lifespan. Both males and females are capable of feeding nymphs, and no family or hierarchy has been observed within colonies; when hungry, nymphs will approach the nearest adult for food.

The creatures that dwell in this rather desolate world still display some diversity in appearance, eating habits, and social behavior. Whether they have fur or feathers, skin or scales, their unique genetic makeup allows for a variety of colors and markings within each species. Despite limitations in food sources, herbivores, omnivores, and carnivores are all present in the food chain, and each species requires specialized care within a laboratory. Although the artificial setting of housing units and breeding pods precludes most opportunities to study true interspecific behavior, the interactions within and between species has been studied extensively in the wilderness by scientists daring enough to venture beyond the outpost’s walls.
